OpenAI

OAKLAND -- Microsoft CEO Satya Nadella said Monday he was &quot;very proud&quot; of his company&#x27;s profitable early investment in OpenAI, as he took the stand in Elon Musk&#x27;s blockbuster lawsuit against the leaders of the AI giant behind ChatGPT.<div><a href="https://www.abs-cbn.com/news/technology/2026/4/25/billionaire-elon-musk-enters-courtroom-showdown-with-openai-1203" rel="noopener noreferrer" target="_blank">Billionaire Elon Musk enters courtroom showdown with OpenAI</a></div>Musk -- an early benefactor of the original nonprofit company -- claims Microsoft knowingly helped OpenAI&#x27;s creators betray their philanthropic mission and turn the firm into a cash cow.The trial has laid bare strife within a circle of elite Silicon Valley engineers, investors and executives in the years leading up to the high-profile launch of the ChatGPT chatbot in 2022.In his lawsuit, Musk accuses OpenAI of betraying its original nonprofit mission and misappropriating his founding donations totaling $38 million to build an empire now valued at over $850 billion.The Tesla and SpaceX founder is calling for OpenAI to revert to its original status as a nonprofit -- a move that would impact its position in the global artificial intelligence race against Anthropic, Google and China&#x27;s Deepseek.OpenAI counters that Musk, who is now an AI competitor with his xAI, is motivated by petty revenge, having stormed off in a huff after failing to seize majority control.Nadella told a jury in Oakland, California, on Monday that Microsoft&#x27;s investment in the nonprofit arm, which now owns around a quarter of OpenAI Group PBC -- the firm behind ChatGPT -- had helped create &quot;one of the largest, most well-funded nonprofits in the world.&quot;Musk&#x27;s attorney said internal Microsoft documents showed the computer behemoth actually had its eye on profit, rather than on helping to nurture a philanthropic AI service, having seen its initial $13 billion investment balloon to be worth $92 billion four years later.<div><a href="https://www.abs-cbn.com/news/technology/2026/4/29/don-t-loot-a-charity-musk-takes-stand-against-openai-0933" rel="noopener noreferrer" target="_blank">Don&#x27;t &#x27;loot a charity&#x27;: Musk takes stand against OpenAI</a></div>&quot;It has worked out well because we took the risk,&quot; said Nadella, of a stake that is now estimated to be worth $135 billion.&quot;If the pie became larger, obviously the nonprofit would benefit as well with their mission — and that&#x27;s what in fact it&#x27;s proven out,&quot; he said.Musk&#x27;s lawyers suggested Microsoft was instrumental in OpenAI&#x27;s pivot toward being a commercial company, citing Nadella&#x27;s 2023 boast: &quot;We have the people, we have the compute, we have the data, we have everything.&quot;<div><a href="https://www.abs-cbn.com/news/world/2026/4/30/-i-literally-was-a-fool-musk-grilled-in-openai-trial-0740" rel="noopener noreferrer" target="_blank">&#x27;I literally was a fool&#x27;: Musk grilled in OpenAI trial</a></div>That year, when several members of OpenAI&#x27;s board ousted company founder Sam Altman, citing a tendency to obfuscate, Nadella moved to shore him up.&quot;I would also try to make sure that Sam and Greg (Brockman, his co-founder) don&#x27;t create a competing company and they would join Microsoft,&quot; he told the court.The morning after Altman was fired, Microsoft had already established a subsidiary company to welcome them and acquire the equity stakes of any employees who chose to follow them — a move one of the co-founders estimated would have cost approximately $25 billion.After a five-day crisis, Altman was ultimately reinstated at OpenAI.<div>&#x27;Making money&#x27;</div>Altman is expected to take the stand on Tuesday or Wednesday, ahead of closing arguments later in the week.An advisory jury is expected to reach a verdict on any actual wrongdoing by the week of May 18.Judge Yvonne Gonzalez Rogers will then make the final ruling on both liability and remedies after hearing the jury&#x27;s opinion. She has indicated she will likely follow their advice.If Gonzalez Rogers ultimately sides with Musk, OpenAI&#x27;s initial public offering could be jeopardized.The trial has already heard gripping testimony.Last week, co-founder Greg Brockman -- whose stake in OpenAI is valued at $30 billion -- came under fire about his 2017 diary entries including one in which he appeared keen on &quot;making money for us.&quot;Musk&#x27;s lawyers seized on the entries to portray Brockman as a calculating opportunist.Brockman also told lawyers that Musk physically threatened him in 2017 after Musk was refused absolute control of OpenAI.<div><a href="https://www.abs-cbn.com/news/world/2026/5/6/elon-musk-was-going-to-hit-me-openai-executive-says-at-trial-1140" rel="noopener noreferrer" target="_blank">Elon Musk &#x27;was going to hit me,&#x27; OpenAI executive says at trial</a></div>Musk on Wednesday announced a major partnership with Anthropic, OpenAI&#x27;s top rival, to allow it to use the compute capacity at SpaceX&#x27;s largest data center.
